why the transformer secondary voltage is more than the load end voltage like t/f 11KV/433V for 415..

Answer / kapil

The regulation of transformer is same as it's percentage
impedance. this means the secondary voltage will drop @ 5%
for a transformer having 5% impedance. to compensate this
internal voltge drop we select nominal tap setting to 433
v. if you keep nominal tap for 415 V, we can not properly
utilize tapping range as 5% is internal drop at full load.

Answer / sriman

The voltage variation between secondary terminals and load
end voltage is because of voltage drop existing between to
systems

why the transformer secondary voltage is more than the load end voltage like t/f 11KV/433V for 415..

Answer / a.k.sen

To compensate the V-drop in the Transformer (considering Impedence value)at full load, Secondary voltage at 433V is selected for load terminal voltage at 415V.

Answer / vishvesh

this difference is kept between transformer secondary and
load terminal because. considering line losses (losses
occurs in the transmission line from transformer secondary
to load).there must be some voltage drop in the
transmission line and also c.t.and p.t. connected across
the line for protection relays also consumes some kind of
voltage from the line.

i want to ask that as everybody knows that in star connection on star point is called neutral. my question is that why on that poin called neutral. what is the reason behind it. what is the logic behind it. i heared somewhere that on this point all phases current become zero thats why. if this answer is right then prove why on that point is current become zero. if this answer is not right then tell me the right answer. post ur answer here or on my mail address. m.ikram786@yahoo.com m.ikram555@gmail.com. thanks.
